    Hello all,

    I currently own a Samsung 3D TV, but I'm not fond of having to use the glasses to see in 3D. I read on this site that there are autostereoscopic monitors, which I assume could be used as glasses-free 3D TV? Is that correct?

    Are there any 3D TV's available to buy at the moment which don't need 3D glasses? From what I understand in the articles I've read here, it wouldn't be possible to have lots of people viewing the same screen and all see 3D, but that should be ok.

    I have one for sale with its stand and brackets. It is a Phillips 42 in monitor stereocopic. Selling for £1500. Cost around £5k when it first came out.

    Are there really auto stereoscopic monitors which I assume could be used as glasses-free 3D TV? I am not sure.But if that is correct then that one is perfect for me.

    I havn't seen a glasses free 3D TV in person. Can anybody comment on how it stacks up to regular 3D?

    I haven't heard of a glasses free 3D TV, either. I guess you had better buy a pair and wait for that stuff you mention to come out. My 3D glasses were bought from SainSonic. You may have a look at it.

    There are several makes on the market but in specialist shops, and not the high street tv Hifi shop. They have improved on the qualities. Quite expensive for the 16 angle view. Mine is just nine. I collected a lot of information / leaflets and magazines from a recent preview in Earls Court. Will find some time to provide the details on this forum soon. Watch the space. Mine was the first ones pioneered but does the job to a high standard. On sale.

    I just watched a Youtube video about the new Dolby/Phillips 4k 3d Glassless display. The guy speaking as a representative of Dolby said that they had eliminated most of the problems of prior attempts with a much larger "sweet-spot" that actually extends far from the center-line for viewing from around the room, instead of having to sit in one spot and not move your head. Not having actually seen one, I'm thinking this is based on a lenticular screen, but the guy reported they are also using a proprietary software and on-board computer to ensure better viewing. He even claimed that the same software could render a 2d movie into a reasonable 3d (but not always with the best results.) Promising video from a trade show, but no mention of how much these are expected to cost once Dolby begins to license them for production.
    This video interview takes place in front of the 3d TV, which is playing while the sales rep and enthusiastic interviewer banter and talk about the set.
    The camera is in a fixed location for the entire interview, sort of making you wonder why they didn't move it from side to side to show everyone the extended lateral capabilities of the set.

    I am very sceptical of this technology, I can see it working fine for a single viewer on things like workstations, laptops and handheld devices like phones and games consoles.

    The problem I see is this, you can't widen a sweet spot, if you have your head in a position where each eye sees the correct image then move your head 2 inches to the left, now your right eye is seeing the image meant for your left eye, or vice versa for moving your head to the right. If by that time, your other eye has reached the next sweet spot then both eyes would be seeing the wrong images which'll result in some serious eyestrain.
    If there's any system which tracks the viewer and makes adjustments so the viewer always sees the correct images the right way round then such a system can only make those adjustments for one viewer and could not work at all for multiple viewers.

    I'd like to be proven wrong but I honestly can't see a practical system for multiple glasses free viewers any time soon. (Having to sit still with your head in a sweet spot for the duration of a movie is not practical to me)
